Bridge City Tool Works Precision Trammel PT-1 Made In USA

Description: Bridge City Tool Works Precision Trammel PT-1. There is some discoloration at various spots. Don’t think this was ever used. All the marks are from storage finger prints etc. I have taken picture along the entire length so you can zoom in and see. The points have a a bit of rust as can be seen from the last pic. Think a scotch brite may remove them (don’t consider myself an expert in tool restoration so did not want to attempt it) I have two of these for sale in separate listings if you buy them both I will combine shipping. From the manufacturers website “PT-1 PRECISION TRAMMEL SET/POINTS/BAR The trammel head without the cursor is always the pivot point (the point you use as a center for your arc), this is the pivot trammel. The trammel with the cursor is always the scribing point, called the scribing trammel. Loosen both trammel points. Lock the scribing trammel head at exactly four inches on the trammel bar rule. Place the scribing trammel point at the FIVE INCH mark on your six inch pocket rule. Now slide the pivot trammel point to exactly the ONE INCH mark on your 6" rule and lock in place. You have just calibrated the PT-1 Precision Trammel Set to exactly four inches. (This technique avoids using the end of the rule, which is bad practice.) As long as you do not change the pivot trammel setting, all future settings of the scribing trammel are accurate. Anytime you sharpen the points, use a pencil, or change the pivot point setting, you will need to recalibrate the scribing point if you wish to use the trammel rule. For those of you using the metric side, repeat the above process using a 10cm spread of the points.” I ship ONLY to mainland USA. I can combine shipping if you communicate promptly and if the items can be shipped together safely. No returns unless the item was described incorrectly - no returns for change of heart etc.
